  • Development of volatile composition and C₁₃-norisoprenoid precursors in Pinot noir grape, Development of volatile composition and C13-norisoprenoid precursors in Pinot noir grape

    Creator:
    Yuan, Fang
    Abstract:
    This study first investigated the developmental changes in the volatile composition and carotenoids of Pinot noir grapes. Grape berries were sampled every week from pea size to harvest during the 2011 and 2012 season. Carotenoids and organic acids were analyzed by HPLC. Volatile compounds were extracted from crushed berries using...

  • The effect of wine matrix on the analysis of volatile sulfur compounds by solid-phase microextraction-GC-PFPD

    Creator:
    Davis, Peter M.
    Abstract:
    Constituents of the wine matrix, including ethanol, affect adsorption of sulfur volatiles on solid-phase microextraction (SPME) fibers, which can impact sensitivity and accuracy of volatile sulfur analysis in wine. Several common wine sulfur volatiles, including hydrogen sulfide (H2S), methanethiol (MeSH), dimethyl sulfide (DMS), dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS), diethyl...

  • Flavor composition of transgenic raspberry bushy dwarf virus-resistant 'Meeker' raspberries

    Creator:
    Malowicki, Sarah Marie-Mahler
    Abstract:
    Raspberries have been popular since the time of the ancient Greeks. Red raspberries are cultivated throughout the world, particularly in the Pacific Northwest region of the United States and Canada. The raspberry bushy dwarf virus (RBDV) causes significant reduction in yield and crumbly fruit in raspberries, blackberries and raspberry-blackberry hybrids....

  • Fruit quality evaluation of strawberries (Fragaria ananassa) grown in California and Oregon

    Creator:
    Jetti, Rajesh R.
    Abstract:
    Five genotypes from California (Ventana, Caniarosa, San Miguel, 13G97, and Venice) and Oregon (Totem, Puget Reliance, Puget Summer, Hood and Independence) were evaluated for quality. The volatile compounds were analyzed using head space solid phase micro extraction-gas chromatography-flame ionization detection (GGFID) and gas chromatography-mass spectrometry (GC-MS). Odor activity values of...

  • Flavor comparison of ultra high temperature processed milk heated by Ohmic heating and conventional methods

    Creator:
    He, Juan
    Abstract:
    Ultra high temperature (UHT) processing can extend shelf life of milk to several months without refrigeration, which is more convenient and energy saving than pasteurized milk. However, the poor acceptance caused by "cooked" flavors limits its marketing growth, especially in United States. Ohmic heating, which has a more uniform and...

  • Composition of Pinot noir Wines Produced from Different Crop Levels

    Creator:
    Li, Jingwen
    Abstract:
    The production of high-quality wine is an important target for wineries worldwide, and low crop level (yield) has been one vineyard management criterion long believed to achieve wine quality. Low yields are most often achieved by removing clusters from the grapevine. Some studies show that cluster thinning can enhance grape...

  • Intrinsic and extrinsic quality of West Coast albacore tuna (Thunnus alalunga)

    Creator:
    Wheeler, Sena C.
    Abstract:
    The purpose of this study is to identify the intrinsic and extrinsic quality characteristics of West Coast albacore tuna (Thunnus alalunga). Albacore tuna were troll caught off the Oregon coast and transferred to the Oregon State University Seafood laboratory in Astoria, Oregon. Core samples were extracted from six designated body...

    Creator:
    Tantasucharit, Usicha
    Abstract:
    The research described in this thesis was aimed at understanding how particle size, porosity, and enzyme accessible surface area influence the rate of saccharification of microcrystalline cellulose. Microcrystalline cellulose (MCC) is a commonly used substrate for the study of cellulolytic enzymes. MCC preparations of different particle size are commercially available....

  • Impact of Pre-fermentation Cold Soak Conditions on Pinot Noir Wine Quality

    Creator:
    Fu, Mengying
    Abstract:
    Wine volatile composition is one of the most important components of wine quality, and it is greatly affected by multiple factors, including grape variety, viticultural practices, and winemaking procedures. Pre-fermentation cold soak is one of the winemaking techniques widely undertaken by winemakers to modify their red wine quality. Imposing a...

  • Hydrolytic methods for the quantification of fructose-equivalents in herbaceous biomass

    Creator:
    Nguyen, Stefanie K.
    Abstract:
    A low, but significant, fraction of the carbohydrate portion of herbaceous biomass may be composed of fructose/fructosyl-containing components (“fructose equivalents”); such carbohydrates include sucrose, fructo-oligosaccharides, and fructans. Standard methods used for the quantification of structural-carbohydrate-derived neutral monosaccharide-equivalents in biomass are not particularly well suited for the quantification of fructose equivalents...
